The Fundamental Step

Cleaning:
The Key to Durability

The success of a protection depends 100% on the initial cleaning. We combine zero-pollution technologies and mastery of Swiss standards to restore your surfaces to their original state, without aggressive chemistry.

Return to the original state, respecting Swiss standards

Our promise is simple: restore the aesthetics of your heritage without ever altering its structure.

We ban the use of aggressive chemicals. Instead, we deploy high-precision mechanical and thermal expertise. The result? A perfectly sanitized surface, a neutral carbon footprint, and total compliance with Swiss environmental requirements.

Exterior Stairs

1. Cold Water High Pressure

Custom pressure, adjusted to the millimeter according to the surface. Our goal is to work with controlled force (up to 300 bars) to extract the majority of urban dirt on stairs, facades, and exterior floors, without ever abrading or damaging the surface.

2. Hot Water Medium Pressure

The essential solution for heavy biological colonization. Faced with green, red, or black stains due to vegetation on your facades or roofs, our thermal unit destroys 100% of the microorganism structure using water heated up to 140°C. Deep disinfection where cold water alone is ineffective.

* Total independence: We use autonomous thermal units capable of generating water at 140°C, ideal for sites without direct access to the electrical or hot water network.

3. Abrasive & Hydro Blasting

The ultimate micro-abrasion technology. By precisely calibrating three parameters — the choice of aggregate, flow rate, and pressure — we perform custom surgical work. This mastery allows us to cover all spectrums: removing a tag from a window without scratching it, stripping multiple layers of thick paint, or micro-abrading a smooth concrete floor to restore a safe, non-slip roughness.

4. Working at Heights (SUVA Standards)

We guarantee interventions at any height in absolute compliance with Swiss safety guidelines. The property owner is thus totally relieved of any legal responsibility. Our operators, specifically trained for rope and MEWP work, deploy the most secure setup according to your building:

  • Telescopic poles (secured work from the ground)
  • Mobile Elevating Work Platforms (MEWP) with mandatory harness
  • Lightweight rolling scaffolding with safety guardrails
  • Fall-arrest PPE and lanyards on certified lifelines
100% SUVA Compliant

Your surface is now sanitized.

The cleaning is finished, but the surface is vulnerable.
We must now apply the molecular shield to perpetuate this result.
